Ubuntu 16.04 Server update crashed web access of openfire 4.5.0

After last update of ubuntu server 16.04 there is no more webaccess to openfire.
Spark logs in, but I can’t see logged in users.

With ios or android app astrachat I can log in and see the users and can write messages.

So what happend?
Update to openfire 4.5.1 worked, but it didn’t solve the problem!
Any help?
Error log is:

Any Help?

Which version of JDK are you using? I’d guess that switch to Java 8 would resolve the problem.

Greg

i think he used java 8…

1.8.0_242 its last java 8 version

OS release upgrade to ubuntu 18.04 solved the problem but crashed php installation.
So I have to setup the server from scratch

I did complete server install from scratch on ubuntu 18.04.
Installed openfire new with mysql database.
logged in an installed the plugins.
I installed the meeting plug in and after that I coud’t log in anymore.
Problem seems it is jitsi:
